OIL-BURNER.

Specification of Letters Patent.

Patented Apr. 8, 1913.

Application filed October 12, 1911. Serial no. 654,294.

To all whom it may concern Be it known that I, CHARLES F. Pownns, a citizen of the United States, and a resident of Birmingham, in the county of J efferson and State of Alabama, have invented a new and Improved Oil-Burner, of which the following is a full, clear, and exact description.

My invention relates to improvements in oil burners, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of my. invention is to provide a device which will burn kerosene, gasolene or denatured alcohol with equal facility.

A further object of my invention is to provide a burner which is simple in construction, and which is provided with a heat retaining portion and a thinner heat conducting portion which may be readily heated to bring the fluid fuel to the vaporizing temperature.

'Other objects and advantages willappear in the following specification, and the novel features of the device will be particularly pointed out in the claim.

My invention is illustrated in the accompanying drawings forming part of the Specification in which,

Figure 1 is a side view of my invention; Fig. 2 is a section through the burner; and Fi 3 is a section through the oil cup.

In carrying out my invention I provide an egg-shaped body, like that shown at A in Figs. 1 and 2. This constitutes the main portion of the burner. It is a hollow casting having a thickened portion a at one end and being provided with thin walls 6, these walls being cast as thin as possible. At the opposite end of the member A from the thickened portion a is an integral threaded tube B,

The member A is designed to be screwed In using the device, the burner is fastened to a plate T or other portion of a stove or furnace by clamping the plate T between the nut N and the shoulder 0 on the part 0. The fuel supply, not Shown, is elevated not more than four feet above the burner proper and is connected with the burner by means of the pipes RP. and P as shown. Between the pipes P and P is a valve V which controls the fuel supply. This valve is opened, thus allowing the oil to pass up into the egg-shaped member A where it passes through the openings a and overflows into the cup-shaped member 0 The oil supply is now shut off by turning the valve, and the oil is lighted in the cup. The member A is heated. The thickened portion a of the member A retains the heat which would ordinarily be radiated if this part were thin. The valve V is now turned gradually and the fluid fuel is vaporized and passes through the openings of which, as stated before, form the outlets for the gas. The device continues to work, due to the fact that the heat is retained. by the part a and is conducted to the thin portion I). I have found that with this construction the burner operates equally as well on denatured alcohol as on the more volatile gasolene, and this is not true with the ordinary burner. Kerosene requires a greater degree of heat to vaporize it than gasolene, and this is secured by the use of a comparatively thick portion which is above the flame and which transmits the heat thus acquired to a thin conducting portion below the flame. The fluid is thus vaporized before it comes into contact with any of the parts that are directly in the flame.

The flanged portion C serves two purposes. It acts as a deflector, and thereby causes the cold air coming from below to pass to one side of the heated walls 6 and prevents the latter from becoming chilled below the vaporizing temperature of the fuel. It also serves as a cup for the preliminary heating of the burner.

I claim In a burner, a hollow casting comprising a vaporizing chamber having thin conducting metal walls provided with perforations at the upper edges of said thin conducting walls, a thickened heat retaining portion surmounting said thin conducting Walls, a the hollow support serving as a means for threaded extension integral with said thin admitting fuel into the interor of said heatconducting Walls, a hollow threaded support ing chamber.
